Exchange 2010 creating massive amounts of logs files at random times

We have Exchange 2010 SP1 RU2 running and at random times the database will just go crazy and start writing many log files a second until it eventually chews up all the free space (it will fill up about 24gb in 2 hours) on the server and crashes Exchange. I ran Exchange user monitor and found the user who was apparently caused Exchange to go crazy this time and he said that all he did was delete a bunch of files from his mailbox. This has happened on a few occasions for different users and the only way to stop the logs is to restart the information store or reboot the server. I am stuck and have no idea what is causing these logs or how to monitor them to see what is causing the issue. Does anyone have any ideas on this? There are also no errors in the event log....

And on another note try to see if one of those users is hosting a spammer on their pc and run a scan on the system.

That link really doesn't help me much because I can get the server running so the backpressure isn't an issue and I don't want to turn on circular logging. What I am looking for is a way to track what is happening so I can stop it.

Managing Active Directory does not always have to be complicated. If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

If you have users with iPhones or Smart Phones using ActiveSync then one of the quickest ways to see if this is the issue is to have users shot those phones off to see if the problem is resolved. If it is one or more iPhones then perhaps look at what IOS they are on and get them to update to the latest version or adjust the activesynce connection timeout. Although I personally would want to know where it came from first.

OK, so it sounds as though my advice helped you in finding the culprit eh?

I know there was an issue with MS CRM Dynamics that caused an issue like this in the past so if you are using the MS Dynamics CRM I would first look for updates to the Outlook Plugin and if that doesn't work then it may be something in the configuration.

Is there a particular KB that documents this issue with MS Dynamics CRM?
